Mystery kitchen device with three finger loops, one attached to a sliding rod that passes through a ring

equipment

This is an oddball question but I am hoping someone can help me identify this device, which appears intended for use in a kitchen based on its location in a drawer full of other kitchen tools. As you can see it is about 4 inches long.

This is a cherry pitter. The metal ring holds the cherry while the piston forces the pit out right through the cherry.
